Product Description




NOTE 2 : If you are ordering a complete drive unit for a 2014+ pickup model please put that in the notes.  The 2014+pickup models have a slightly different frame and use plastic drive unit top cap with circuit board.  We can build it up for that but just need to know if ordering complete drive unit for 2014+ pickup model.  Put that in the notes of the order please.

NOTE 3 : *** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***

** 2 Options Are Available ***

Note that if you chose Option 2, you will either need to send in your unit for repair directly, or wait approximately 2 months for us to get a unit to repair.  These are becoming hard to find and people arent returning their cores as often anymore for some reason.  We can usually repair sent in units same day to minimize down time as you cant install the mirror without the drive unit in place.

Option 1: 

Buy strengthened steel gears machined integral to the main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  

Option 2:

Buy a rebuilt complete motor drive unit with new hi-torque motor + steel integral gear already installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.

***** PLEASE NOTE WHEN ORDERING THE COMPLETE DRIVE UNIT - If you are in a hurry for this, its best to check with us to see if we have any cores.  It could be 4-6 weeks to receive this, based on how many units we have in the shop.  People do not send back their cores very quickly, so we are usually waiting.  You can send in your own unit to be worked as well, and we will apply the $30 core when you send in and try to work it same day or very quick.  


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened STEEL gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on most 2007-Present GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened integral spiral spur/worm gear shaft made from high strength steel to eliminate the fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can chose to buy the gear/motor combo for one or both sides or you can buy complete drive units which are rebuilt and already have the new metal gears and hi torque motor installed in them.  

We have thoroughly tested our redesigned integral gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.


** Application ** 

Gears and Motors Fit Both Passenger and Drivers Side Power Folding Mirrors.  

All 2007-Present GM Pick Up Trucks Including all Silverado and Sierra with Non-Towing Power Fold Mirrors -- please note the 2014+ pick up trucks used different plastics on the frame, so disassembly of the mirror frame doesnt match the previous gen DIY.  The lower half of the drive unit with all the gears inside IS the same as the previous generation.

All 2007-2014 GM SUV's With Power Folding Non-Tow Mirrors Including Acadia, Traverse, Enclave, Escalade, Tahoe, Suburban, Yukon, and Denali. 

This includes (but not limited to) the following mirror assembly part numbers :

25-83-12-36 (25831236), 25-77-98-49 (25779849)

This list of part numbers will continually grow as we build the interchange list.  This is in no way complete, as most GM trucks made from 2007-2014 with power folding mirrors will use this gear.  If your power folding mirror looks like the mirror shown in the DIY, this gear will fit your vehicle.


... We also have many more products for GM, including the towing mirror gears, 2015-Present SUV non-towing mirror gears, door lock motors, door handle inserts !  Check out the GM section of our website!

  1. GM folding mirror motor replacement 5 Star Review

    Posted by on 27th Feb 2024

    I purchased 2 motors and gears to repair my broken folding mirrors. The u tube video from gruvenparts was very informative and when I had a question I emailed them and they quickly responded. The motors and gears performed as they should and my mirrors now function.

  2. Lot better than $500.00 for a complete mirror 5 Star Review

    Posted by on 24th Feb 2024

    a little tuff getting the mirror off and back on
    also hard getting the loaded spring assembly apart and back togeter
    i bought a 2 foot of 1" PVC pipe for $5. to pust down on spring assembly and worked perfect for taking it apart and compressing and putting it back together

  3. An excellent improvement 5 Star Review

    Posted by on 22nd Feb 2024

    After following the tutorial for changing, the switch over went smoothly. The mirrors are smoother and much faster than original. I would and have recommended your product to others as this seems to be a common problem. Well done!!!

  4. Great Product 5 Star Review

    Posted by on 10th Feb 2024

    Much cheaper than buying the whole driver side mirror from the dealer. Easy installation. Will purchase again when the passenger side breaks.

  5. Great upgrade to an OEM Problem 5 Star Review

    Posted by on 11th Jan 2024

    After several folding mirror movement failures, I opted for the upgraded motor and gear assembly from Gruven Parts. Installation was straightforward thanks to the YouTube videos, and after the installation was completed I was utterly impressed with the smooth (and fast) operation of the new motor assembly.

  6. mirror parts 5 Star Review

    Posted by on 9th Jan 2024

    I have installed these parts before and they worked great. Have not got these installed yet. I ordered these because the other set has worked perfect. Will order again if needed.

  7. LONG Time Shipping 3 Star Review

    Posted by on 4th Jan 2024

    This is my second order from Gruven Parts and I know the quality will be there in the parts I ordered. The only problem was the shipping time. Understandably since I ordered on Christmas Day I knew there would be some delay with the New Year as well. I got a Post Office tracking number the day after Christmas. I kept checking with the Post Office but they were not receiving the part from Gruven. Finally on January 3rd I contacted Gurven to ask why and was told that the Post Office would be receiving it that day.

    Now on the 4th of January Gruven wants me to review the part I haven't received. As already stated I am sure the part will be excellent; just not the shipping.


    Sorry Lea. Orders on Christmas can take a little longer since USPS is often understaffed. This year, we all got Covid for Christmas too, added bonus!

    Im glad you have the parts now and sorry for the delay. Please contact me before your next order, we will make it right.

  8. Good quality 5 Star Review

    Posted by on 1st Jan 2024

    The gear and the motor they look stronger than factory parts, I installed them like in the gruvenparts is and now my mirror is working like new again

  9. The Best Fix. Working Perfectly!!! 5 Star Review

    Posted by on 27th Dec 2023

    Replaced both sides. Replacement video was great. Everything is working perfectly.

  10. Excellent Product 5 Star Review

    Posted by on 19th Dec 2023

    Purchased the two gears and motors. Put installation video on laptop and set it up in the garage. Followed the instructions of the video step by step and replaced the broken plastic gears and motors in the 2008 Avalanche and both work like a charm. It takes a while to disassemble the mirrors and release the spring, but instructions help make it doable. Great satisfaction in seeing them operate again. as they should.
